Lightroom 6 crashes when hardware acceleration is enabled on AMD dual graphics

On an HP laptop running Windows 8.1 64-bit with AMD Radeon HD 7620G + Radeon HD 8670M dual graphics, Lightroom 6 crashes randomly only when "Use Graphics Processor" / hardware acceleration is enabled. The discrete 8670M is set as the primary adapter, the drivers are updated, and Lightroom's System Info reports the GPU meets the OpenGL requirement. With hardware acceleration turned off, Lightroom is stable. Is this a known issue with AMD dual-GPU setups, and are there any troubleshooting steps besides leaving GPU acceleration disabled?

Firstly check that in the AMD panel you can configure which graphic card is used when Lightroom is started.
Perhaps disable one of the graphic cards before starting Lightroom.
Moreover, a good solution is to completely uninstall the drivers, clean them, then reboot and install the drivers again. This is just to be sure you have a "clean install" of the graphic driver.
Check also that you put Lightroom on the exclusion list of your antivirus software...

Yes—this has been reported with some AMD GPU/driver combinations in Lightroom 6, especially on systems with switchable/dual graphics. If Lightroom is stable with hardware acceleration off, the issue is likely the GPU/driver interaction rather than Lightroom itself.
Things to try:
- In the AMD control panel, make sure Lightroom is forced to use one GPU consistently, preferably the discrete card.
- If possible, temporarily disable one of the GPUs and test Lightroom again.
- Do a clean reinstall of the graphics drivers: uninstall, clean out the old driver, reboot, then reinstall.
- If you already have the newest driver, try a different driver version—newest is not always the most stable for Lightroom.
- Add Lightroom to your antivirus exclusions in case background scanning contributes to instability.
Also, GPU acceleration in Lightroom 6 does not always produce a dramatic speed gain; for some users it can even feel less responsive. If the above steps do not help, leaving GPU acceleration disabled is a reasonable workaround until a better driver/update is available.
